Victoria Nuland already did that in 2013-2014. That's why we're here now.

There's even proof. Wikipedia published the quote below, and claimed it was Russian Propaganda that the US was involved. That absolutely seals it that Nuland and the USA was involved.

In December 2013, Victoria Nuland, the US Assistant Secretary of State for European and Eurasian Affairs, said in a speech to the US–Ukraine Foundation that the US had spent about $5 billion on democracy-building programs in Ukraine since 1991. The Russian government seized on this statement, claiming it was evidence the US was orchestrating a revolution. In February 2014, a phone conversation between Nuland and US Ambassador to Ukraine Geoffrey Pyatt was leaked. Nuland and Pyatt discuss who they think should or should not be in Ukraine's new government and give their opinion of some Ukrainian political figures. US Department of State spokesperson Jen Psaki said the discussion was not evidence of any plan to influence the political outcome, saying "It shouldn't be a surprise" that politicians would discuss the revolution and Ukraine's future leadership. Yale University professor Timothy Snyder said, "Imagine just how much evidence the Russians have of what the U.S. was doing in Ukraine, given that they had access to that telephone call. That was the best bit they could come up with. And in the context of the time, what that telephone conversation showed was that the Americans were, A, not up to date about what was happening in Ukraine and, B, unable to influence events happening in Ukraine."
